May 12, 2008
We took the quiz and then discussed the homework and DeMoivre's Theorem (newest HW answers here: complex hw2 answers.pdf)
We discussed the complex number homework that we've been working on (newest HW answers here: complex hw answers.pdf). This led to a neat theorem to find the powers of complex numbers.
We began by looking at plausible functions from last class (the four XC problems) and connected them to the polar graph symmetry from last homework (and the parametric equations from last homework). We also looked a little more at the homework from last class using the Sketchpad polar-Cartesian sketch. We then discussed complex numbers- rectangular form and the Argand plane, conjugate, argument and modulus. This led to the polar form from last night's homework. We investigated why this form is very nice using this sketch (Complex Multiplication 2.gsp).
Quiz moved to next Monday and Friday due to AP exams (can count one or both)
May 2, 2008
We took the Supercorrection follow-up quiz, explored some plausible functions, went over the homework (answers: polar hw answers.pdf).

Tues/Wed, September 4/5th
We thought about the following...
For each of the following problems, first estimate an answer and then try to calculate an answer using your mathematical skills.
When was one million seconds ago? How about one billion seconds ago? For more on this problem, click here.
Suppose a string were tied tight around the earth. If one additional meter were added to the string, and the string was lifted the same distance off the surface of the earth, how high would it rise? For more on this problem, click here.
If a piece of paper could be folded in half fifty times, how high would the stack of paper be? For more on this problem, click here.
If you're interested in how we name large numbers, click here.
Read the course methodology and come to class prepared to discuss it (a copy is available on the home page of this website).
Give the parent/guardian letter to your parent/guardian (again, a copy is available on the home page of this website).
Please complete this student information sheet (you won't be able to submit this unless you have all information- including a wikispaces username, parent email address, and textbook number).

Tues/Wed, September 4/5th
We thought about the following...For each of the following problems, first estimate an answer and then try to calculate an answer using your mathematical skills.
- When was one million seconds ago? How about one billion seconds ago? For more on this problem, click here.
- Suppose a string were tied tight around the earth. If one additional meter were added to the string, and the string was lifted the same distance off the surface of the earth, how high would it rise? For more on this problem, click here.
- If a piece of paper could be folded in half fifty times, how high would the stack of paper be? For more on this problem, click here.
